Title: Method and device for pb signal reception
Inventor: MIZUGUCHI TADASHI
IPC: H04Q1/45
Filed: 1990-01-18
Abstract: PURPOSE:To speedily cut a dial tone at the time of first figure dialing and to prevent a PB signal from being mixed into a prepared speech path after the end of dialing as well by announcing figure information to an exchange control part at the time of rise for the first digit of the PB signal and at the time of full for digits after the second digit. CONSTITUTION:When a reception instruction is received, a monitor circuit 7 sets the digit information stored in a storage circuit 8 to 0. Afterwards, a PB signal detection circuit 6 is periodically monitored and each time one digit of the PB signal is detected, the information are incremented. The detection/stop of the PB signal is monitored and simultaneously, a detected result showing the corresponding figure information is stored in the storage circuit 8. Concerning the first digit of the PB signal, the monitor circuit 7 announces the figure information corresponding to the detected result to a central processing unit 9 immediately after confirming the detection of the PB signal by the PB signal detection circuit 6. Concerning the digits after the second digit of the PB signal, when the stop of the PB signal is recognized, the figure information stored in the storage circuit 8 corresponding to the detected result at the time of reception are announced to the central processing unit 9.

Title: Main storage key storing system
Inventor: YOSHIDA AKIRA
IPC: G06F12/14
Filed: 1994-02-01
Abstract: PURPOSE:To prevent increase of the hardware quantity of a main storage which stores the main storage keys despite increase of the storage capacity of a main storage. CONSTITUTION:When the capacity of a main storage 3 is large, all main storage keys are stored in a key storing area 31 of the storage 3.

Title: Avalanche photodiode
Inventor: TORIKAI TOSHITAKA
IPC: H01L31/107
Filed: 1989-01-18
Abstract: PURPOSE:To set a low dark current and to improve ionization ratio by composing a semiconductor period structure of an AlxGa1-xInAs composition change layer and a GaAs uniform composition layer, and forming a maximum conduction band discontinuous part of GaAs and GalnAs. CONSTITUTION:A period structure is composed of an AlxGa1-xInAs composition change layer 3 having a relatively small Al composition and a GaAs layer 4. In this case, the more the Al is contained, the greater a dark current increases remarkably. Accordingly, the dark current can be reduced by substituting the part having relatively more Al composition for the GaAs layer 4 without using AlInAs containing largest Al. Since electrons accelerated in the AlGaInAs composition change layer 3 having relatively small Al composition can easily clear a conduction band barrier DELTAEc' (-0.1eV of small value) with the GaAs 4, the deterioration of a response can be ignored. Further, since the conduction band discontinuity DELTAEc of the GaAs 4 with the GalnAs is larger than that of a conventional AlInAs, the ionization rate of the electron is increased. Thus, high sensitivity in which a low dark current and ionization ratio are improved is provided.

The impurity is preliminarily added to the raw material prior to starting of the growth of the single crystal and thereafter the growth is started. The output of the heater 7 is regulated to melt the upper part of the raw material solid 3 by as much as the amt. approximately equal to the amt. of the grown single crystal or T(coefft. of segregation) X weight of the crystal in order to compensate the impurity concn. in the raw material melt 4 increasing with the growth of the single crystal.

Title: Swirling flow type melting furnace
Inventor: HONDA HIROKI
IPC: F23G5/24
Filed: 1989-01-23
Abstract: PURPOSE:To improve the slag recovery factor by providing a burner which is provided along the substantially tangential line to the inner face of a furnace at the position of a specified height from the level of a slag hole in the bottom of the furnace and into which powdered sludge, etc. are charged and a supplementary burner which burns with oil, gas, etc. and is operable. CONSTITUTION:In the starting firstly oil, gas, or other fuel is jetted out from a supplementary burner 6 and ignited. At the same time powdered sludge, etc. are blown into a sludge burner 5. When the temperature has reached natural temperature, the supplementary burner 6 stops injecting the fuel. The inorganic portion in the powdered sludge that has completed combustion attaches to and is caught by the furnace wall 2 by the centrifugal force of the swirling flow 9, and another portion forms a solid slag 8 to protect the furnace wall 2. The rest becomes liquid slag 7 and flows down on the furnace wall 2 and reaches the furnace bottom 3 to become a fluid slag 10 in the furnace bottom. Then it is discharged downwards from a slag hole 4 and recovered. The viscosity of the fluid slag 10 in the furnace bottom is liable to rise, but since the sludge burner 5 is located at the height in the range of 120-300mm from the furnace bottom 3, the radiation heat from the sludge burner 5 heats the fluid slag 10 in the furnace bottom and it maintains a high fluidity so that it is discharged fully from the slag hole 4.
